Bungee Energy Check In

What is the most important physics principle behind bungee jumping?

• The law of conservation of energy

  (total energy never changes)

• The law of inertia (object at rest will stay at rest unless an outside force acts on it)

• Newton's 2nd law of motion (F=ma)

• The law of gravity

In position 1 of the bungee jump, what type of energy does the jumper have?

• Kinetic energy

• Thermal energy

• Gravitational potential energy

• Elastic energy

In position 2 of the bungee jump, gravitational potential energy (Eg) is transforming into ___ energy.

• Elastic energy

• Thermal energy

• kinetic

• Chemical energy

In position 3 of the bungee jump, what type of energy is starting to transfer to the bungee cord?

• Kinetic energy

• Elastic energy

• Gravitational potential energy

• Thermal energy

In position 4 of the bungee jump, what type of energy is mostly present?

• Gravitational potential energy

• Thermal energy

• Elastic energy

• Kinetic energy

What situation would someone have the most gravitational potential energy (Eg) present?

• Someone on top of the empire state building

• Someone when they are mid jump

• Someone falling down the stairs

• Someone who just ate a lot of food in the cafeteria

Match the following energy types to their definitions.

• Heat or friction.

• Kinetic energy (Ek)

• Bonds from atoms

• gravitational potential energy (Eg)

• Moving!

• Elastic potential Energy (Ee)

• being stretched out

• Thermal Energy (Et)

• Being high up off the ground

• Chemical potential energy (Ec)

The bungee jumper slows down and loses kinetic energy near the bottom of the jump because...

• It is lost to heat

• The kinetic energy is transformed into elastic energy in the bungee cord

• The jumper gets tired and so they lose kinetic energy

• They are closer to the ground so kinetic has to decrease

In your opinion, what type of energy makes bungee jumping the MOST scary? (this is a silly question with no specific right answer)...
